Be it known that 1HENRY L. DAY, a citizen of the Unitedl States, resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements yin Fireplaces, of which the following is a specification.

My invention has for itsjobject to provide a fireplace heater in which the lirechamber and the products of combustio-n flue leading therefrom" will be formed in sections and a casing formed of sections and enclosing the replace heater and combustion flue and adapted to be set-up or installed in a room, without being set into the brick or masonry constituting the chimney, thus making it possible to form the various parts in the factory and ship them in sec,- tions ready for installation and affording a greater radiating heating surface in the room in which installed.

The fireplace ychamber l is of lthe' usual form and is preferably provided with a base` 2 formed of brick or tile, with a rear wall', backwardly inclined side walls 4 4,l and an inclined top wall 5, at the fronty ofl which is preferably located an exit 4opening 6 communicating with a smoke box .7 forming the lower section'y of the conduit o-r Hue for the smoke and products of combustion. Said 'smoke box is preferably providedwith a suitable damper 8 by which .theA opening from the fireplace tothe smoke box may be regulated. v i Y The smoke boX 7 is preferably in the form of a-flattened cone, the lowere'n'd being of substantially' the IWidthl of the'iireplace "chamber and tting over the/smoke openlngof said chamber (Figures y1l and'). Said smoke boX is alsopreferablyprovided with a horizontal Wall 9, partially closing its lower end, and forming af broad base. yby 'which ythe boX is supported upon the top of the fire chamber. vA water back 10i-is secured to said chamber as hereinafter described. ,Thel damper 8 is preferably'pivo-tally secured to the4 horizontal wall 9 of thei-'fl smokeboX 7 as shown in F igure The smoke boX 7 is preferablvfo-rmed of copper and made in two longitudinal sec- 4tions ,fprovide d with flanges 11-,11, secured to ether by@ Series of bolts 12and1111.11'51513?vi igure 9). This construction 'perm-its said smoke boX tobe shipped in a nestedcondition and assembled at'the placeo-f erection.

- The walls?) and 4 ofthefir'e chamber lare provided with flangesy 14 betweenfwhichrl `prefer to arrange an' asbestos strip '15, with preferably' formed of sheet copper, andare strips of band iron 16 arrangedoutsideof l the iianges, and bolts 17 provided with nutsv '18 holding said vpartstogether (Figure 1 0).

Byusing copper sheets forthewallsof the fire-chamber 'andffor the smoke box-the heat fis more eiiiciently radiated from the outer surfaces of said sheets into the surrounding yair chamber as hereinafter de-Y scribed, as-copper is ya good heat conductor.

' Moreover, the copper sheets are durable and will not rust. f Thelower part of the fire chambermay be lined in the customaryway'with`- firev clay4 or other 'suitablelining Arranged-above v.the smoke box 7, and forming vay continuation of the smoke flue, T preferably provide a series ofl double conical "sheet VAmetal heat radiating drums 19, provided with tele'scop' ,'Iing end sections QOand 21 (Figures 6 and Any suitable 'fnumberfof 'fth'esedrums may .be employed. I have lslitwvn'in the drawingsive suchk drums, but Aa''greater or less number may be used as desired.- The upper drum connectsiwith a smoke pipe 22 that leads. to a chimney or other, suitable smoke flue, by which the products ofY com;l

bustion may be conducted to the outside air. The products of combustion or hot ygases passing fro-1n the fire chamber enter the` smo-ke box 7 and pass upward into the lower drum 19. Thewalls of the smoke box are heated by the said products of combustion. The hot gases expand in eachof the drums and heat the drum walls. The heat edrwalls of the smoke box and drums heat the airl in. the surrounding chamber, as hereinafter. described.

Surrounding the lire chamber, the` smoke box, drums, and smoke flue, hereinbefore described, I `provide an air heating chamber, which is arranged to permit air,` either fromI the room in which the fireplace is located,'or `from out of doors, or both, to enter the lower part of the chamber andpass- `ing' upward therein to be heated from the walls of the, fire chamber, smoke box and drums, andv after being` sov heated to pass outward into the upper-part of the `room in whichl the fireplace is located. By this lmeans the heat from the walls of the fire chamber, smoke box and drums, is trans- .-mitted by. convection to the room toy be heated, which. is preferably the room in which the `fireplace is located, The room is, therefore, heated ydirectly by radiant heat-from the open fire in the fireV chamber,

fandzalso by, convec-ted heat throughk the air `chamber partially surrounding the fire chamber. Y

Theibaekof. the air chamber 23 is preferably; formedby avvertical wallk21l, which mayA be a wall of the room in which the fireplace is located. This may be an interior or an` exterior wall of vthe. building. InEigures 2 and 3 of the drawings l have indicated an exterior-wall 'of the building asconstitutingthe rear of the air chamber 23., Tfhebottom of the air chamberis preferably formed by the floorv25 of the room in which the fireplace is located, and the top ofy the chamber by the ceiling wall 26.

The frontl and end walls of the chamber 23 are preferably formed of removable panels, with the front panelsy arranged at` the sides and above the fireplace opening (Eigures 2l ande). As here shown I provide upright studs or-corner posts 27 forAsaid air chamber 23.

e These posts -Inaybe located so as to pro-vide za chamber 23 ofrany desired size.

Securedto-the posts 27 4are the series of imperforate panels 2 8, each of said panels` being preferably composed of an imperforate sheetof wood, asbestos or fiber board 2.9,. orV a combination thereof, withV asurrounding frame 30, One or` more of the panels may be provided with a central secter 35.

I may also provide a cold' air flue 37 connectingvvith the lower part of the air chamber, 23 (Figure 3). This'air flue may be provided lwith a valve or damper 38, and with, a wire mesh covering 39. By means of this. damper the amount,r of cold air entering tlie lo-werpart ofthe chamber may be regulated. It will 'be seen that with this arrangement the'v air from the room, or from l outside, Lmay bepermittedto enter the lower part of--the vair chamber 23, and it will then pass up and come into contact with the firey chamber, the smoke box 7 and the drums 1,9,v and becoming heated in 'said chamber it will pass. out through the open panel into the room tobeheated. This may be the room in which the fireplace is located or if preferred this heat. may becon-L ducted to any other room or apartment-that it is desired to heat..y

I also prefer to providevmeans by which be heated from the fre chamber, either Vthrough water heated bythere in the re chamberV or by steamgeneratedby said fire.

.l1 have shown inthel dra/wings ahot water back 10 locatedl against'the upper part of Vthe fire chamber, andr providedwith rwater cir- 'culating pipes 40, extending to suitable radiators l1,.withzreturn l pipes 42, extending to said water back. Apip'e disdesigned to be. cor'l'n'ected"` to' ay suitable expansion chamber (not shown) The radiators maybe located at anyV `desired point. I'have ,here shownpthem located in compartments43 arrangedV within the,y

breast of the fireplace, and provided with inlet and outlet openings ,44 and 45", for the passage of air through'l said' compartment, and in contact with said'radiators. rlhese `rad'iat'orsmay, however, without any change 1n principle be located at any desired poin ,i in the. room or rooms to' berheated,

radiators located' at any desired point may The smoke box7ispreferably constructed *i as` shown to provide` an expansion space to intercept anyiwlndfor downward icurrentsuin. the smoke flue.

,Y A Ysuitableb1ower-4=7` maybe fa'rlrahgedito closeor partially. closethe front offthefire chamber., Thisvblower -may be suspended and counterbalanced as by cords 48"and Weights 49 so as to be easily moved and held at any desired position.

Suitable means such as a pipe 50 connected to the Water back 10 and having a valve 51, may be provided for supplying Water to the Water heating elements.

The heated air from the air heating chamber may be delivered in Whole or in part to one or more other rooms than the one in which the replace is located. Conductors with dampers may be arranged to divert the Warm air as desired.

The details of the construction may be varied in many particulars Without departing from my invention.

I claim as my invention:

l. An open lire-place heater comprising a lire-chamber with an open front and formed of separable plates constituting its side, rear and top Walls, a smoke-box in communication with the top of the lire-chamber and separable therefrom, a smoke-flue consisting of a series of independent sections connected with the smoke-box and separable therefrom, all of said parts being formed of heat conducting material, and a casing inclosing the lire-chamber, smoke-box, and smoke-flue, and forming air-chambers at opposite sides and at the rear of the fire-chamber, and around the smoke-box and smoke-flue, and having air inlets in the lower portions of its wall, the structure being adapted to be installed in a room outside of the usual chimney construction.

2. An open fire-place heater comprising a lire chamber having an open front, a smokeboX in communication with the fire-chamber, a smoke-Hue connected With the smokebox, a Water heater formed as a part of the open front fire chamber, vvaterv circulating and return `pipes connected With the Water heater, and a casing enclosing the open face lire chamber, smoke-box, smoke flue and Water heater and composed of sectional separable panels adapted for installation in a room outside of the usual chimney construction.

8. An open hre-place heater comprising a re chamber having an open front, a smoke boX in communication with the fire-chamber, a smoke lue connected with the smoke-box, a Water heater formed as a part of theopen front fire chamber, radiators, Water circulating and return pipes connecting the radiators and Water chamber, and a casing formed of sectional panels enclosing the open face fire chamber, smoke box, smoke flue, and vradiators and adapted to be installed in a room outside of the usual chimney construction.

In Witness whereof, I have hereunto set my hand this 14th day of November, 1921.
